Cross check

For cross checking the same steps as described in section should be carried out as soon as possible, but should not take more than five working days. Moreover it should be checked if integrated tools correspond to the adopted proposal. Results of cross check should be announced to the reflector. The result-sheet should be made available to the group.

2. Procedure if cross check fails or planned delivery data cannot be held

If a planned delivery date cannot be held this should be announced to the reflector.

If the crosscheck fails or the previous integrator has not delivered the software within 3 days or result sheet within 5 days after planned delivery date

• 
  The current integrator should integrate in the last cross-checked version
  
• 
  The previous integrator falls back to the end of the integration plan
  

3. Software repositories

   1. HTM

HTM software can be checked in

https://hevc.hhi.fraunhofer.de/svn/svn_3DVCSoftware/

Therefore for each integrator an own software branch will be created by the software coordinator containing the current anchor version or the version of the previous integrator:

e.g. branches/0.7-mycompany

The branch of the last integrator will become the new release candidate tag.

e.g. tags/0.8rc1

This tag can be cross-check by the group for. If no problems occur the release candidate will become the new tag after 7-days:

e.g. tags/0.8

If reasonable intermediate release candidate tags can be created by the software coordinator.

2. ATM

An official release of the 3DV-ATM software can be check out by mpeg3dv SVN users from the following location:

http://mpeg3dv.research.nokia.com/svn/mpeg3dv/trunk/

Following every MPEG 3DV meeting, software coordinator creates a new branch for the integration of adopted proposals:

http://mpeg3dv.research.nokia.com/svn/mpeg3dv/branches/mpeg10X_post_integration/

Software integrator checks-out the software from integration branch at its turn of integration plan and integrates proposal as it is specified in Sections 3.1–3.2.

Software integrator communicates a new software version over the email list to the cross-checker and to the software coordinator.

The software coordinator checks-in to the integration branch every new software integration with confirmed cross-check, as it is specified in the Section 3.3.

Once the integration plan is completed, the software coordinator cross-check version available in the integration branch and checks-in a new official release of the 3DV-ATM to the http://mpeg3dv.research.nokia.com/svn/mpeg3dv/trunk/.
